I have configured the following access-list on routers fa0 interface (i am using 1801)
access-list 111 permit ip any any log
and applied it in "in" direction on Fa0 interface.
Now when i am sending ssh packets to this interface its showing below
*May 14 05:09:00.104: %SEC-6-IPACCESSLOGP: list 111 permitted tcp 172.18.128.2(0) -> 172.18.128.146(0), 1 packet
why its not showing any port number ?
I have a cisco 1801 (fixed), and want to use the fe0 WAN port to connect to the internet via a virgin media cable modem.
I am having a few issues (partly as I am new to cisco) and despite reading numerous posts both here and other sites, I am still stuck on how to setup the WAN side, I have read about virtual dial up & dialer interface.
We have IP device on the farm switch(cat6500, which is an access layer siwtch), with the gateway on the core switches (Nexus7000), on the core when I do show ip arp, I found the mac.But when I do sh mac add add of that mac there is no port attached to that mac.
Since that particular vlan only resides on the cat 6500 and two cores, so I logged in to the 6500, and when I show mac- in that vlan, I didn’t find that mac addresss. Instead, I found another mac address with last 8bit are the same of that mac.
Is it some kind VIP of the mac? How so, if no port, how can the switch forward the frame? [code]
Clarifying whats the correct # of port asic in WS-X6704-LC?According to the following link (Catalyst 6500 Architectural white paper): [URL]
"In the WS-X6704-10GE line card, there are two port ASICs each supporting 2 x 10 Gigabit Ethernet ports"
While in the document: Understanding Quality of Service on the Catalyst 6500 Switch: [URL]
Table 10.
WS-X6704
Number of 10 GE Ports 4
- QoS on 10-Gigabit Ethernet Line Cards (WS-X6704-10GE)
So whats correct? 4 port asic or 2 port asic?
# Port ASIC’s on the linecard 4
# Physical Ports per Port ASIC 1
Are you only able to have two sessions for port mirroring on a Cisco 4510?
View 1 Replies View RelatedI'm developing a project where I use the SNMP protocol to discover the network. By discovering the network I mean go through all the routers and switches and retrieve the IP routing table from routers and the forwarding table from switches. With the routers I have no problem. For the switches I need to know for each port the MAC addresses and the Vlans. Basically it's use SNMP to find a port number from a MAC address. To do that i followed this tutorial: [URL]
The problem is that I'm using a Cisco 3725 Router with IOS 12.4 (21) and a NM-16ESW module to work as a Switch and when I use the OID .1.3.6.1.2.1.17 corresponding to the BRIDGE-MIB as it follows:
snmpwalk -v2c -c myrouter 10.1.1.5 .1.3.6.1.2.1.17
it returns:
SNMPv2-SMI::mib-2.17.1.1.0 = Hex-STRING: 00 00 00 00 00 00
SNMPv2-SMI::mib-2.17.1.2.0 = INTEGER: 0
SNMPv2-SMI::mib-2.17.1.3.0 = INTEGER: 4
From this I guess there's no information on the router about Vlans or anything. Other thing is that when I use community string indexing it returns a timeout. My theory is that this version doesn't support indexing but I don't know.
how can I get the Port Number from a MAC address from this "switch" (it's a router working as a switch) using SNMP?
I'm in the middle of a Nexus 5000 project and recognized today while configuring port-channels, that some of the interface numbers are reserved for internal use.
Is it possible to change or configure which port-channel interface numbers are allocated for internal use by NX-OS?
Unfortunatly I wasn't able to find a solution for this issue in the offical Nexus documentation, the search function of this forum or Google. If I did miss something or didn't look careful enough at the Nexus docs, I'm also happy with RTFM (... fine manual) responses and links to the info :-)

Now I want to add a static route to go out that interface.when I add: ip route 10.x.x.x 255.255.255.0 10.52.10.1
it eccepts it (no errors) But, it does not show in the routing table nor in the config? How to add the static route to go out that vlan interface.

I have cisco 1801W . Earlier I am using ADSL dynamic IP address on RJ 11 through the ADSL Port but now the ISP change the connection to RJ45.
I am trying to configure it but unable to do this. ADSL line is okay because When I am connecting through the ISP router it is working fine. I have connected the ADSL RJ45 cable in the router fast ethernet 0.But I wanted to use Cisco 1801 Router so that I can use the ADSL as primary and ISDN as the backup.
Below is my configuration, eiteher this is possible to configure ADSL through RJ45 in 1801 and what configuration require for this.

I am wondering what are the limits per routers for creating the vlans in vlan database? I have a 1801 router with the c180x-broadband-mz.151-3.T2 IOS and cant create more than 14 vlans.. How many does 2800 router support? Why I can't find this information anywhere on cisco.com?

View 11 Replies View RelatedI've recently purchased a Cisco catalyst 2960S-24TS-L & setup 3 V LANS 10 (no current IP),20 (192.168.2.1) and 30 (192.168.3.1) to reflect the router V LAN configuration & ip information. When connecting my PC to the switch to test connectivity on (2.1 & 3.1) I'm unable to connect to the the net but can successfully ping GW (int FE0.20 & FE0.30) 192.168.2.1 & 3.1.
The router is an Cisco 1801 & it seems this is where the configuration issue is but I'm unable to figure out how to complete the setup. It has been quite awhile since I've configured a Cisco router.
Ive never had this router connected to a switch so all router switch ports are in the default VLAN1 (192.168.1.2), with FE0 disabled. In trying to get the switch to communicate with the router I made the following router config modifications.
FE0 enabled with subinterfaces configured
FE0.10-currently no ip
FE0.20-192.168.2.1/27
FE0.30-192.168.3.1/27
I have two issues I want to resolve:
1) I do not know what additional steps are required to allow 2.1.& 3.1 V LANs to access the net.
2) I want to disable VLAN1 if possible & use the network IP for VLAN10 (192.168.1.0). I'm unsure how to do this as any change on VLAN1 immediately breaks router access and the router reconfiguration becomes more complicated with changes to the FW ACL etc.
Can a Cisco 1801 FE0 port be sub-interfaced?

We have the need to create a large number of VLANs on one of our networks. We're talking about 60! These will all terminate on a pair of 6509-E switches (building core). We use MSTP as a standard on our network so I'm going to stick with that so that we can dramatically reduce the number of STP instances needed. However, regarding the SVIs (default gateways) is there any reason why creating 60 of these guys would be considerd a big no-no? Or would you expect the 6509s to deal with them like a boss?
